I have been struggling a bit with the first shot double action pull on the Sig, and with time and practice I expect that to change.

If you don't like the DA/SA, you can send you gun to Sig and they'll convert it to their DAK (if you don't know what it is, basically, it's DAO) system for $200. It's a lot of money, but could potentially make the gun more usable. Of course, the other option is just to practice. My wife has a DA/SA SP2022 and my father in law has a P229, and I can't stand shooting either of them for that same reason. I have nothing against Sig, per se, but they aren't for me.
